Abstract

Technology for a next generation node B (gNB) operable to measure crosslink signal-to-interference ratio (SINR) in a dynamic time division duplex (TDD) new radio (NR) system is disclosed. The gNB can encode a downlink interference measurement reference signal (IM-RS), for transm 5 ission to a first user equipment (UE), in a selected comb of an IFDMA comb structure. The gNB can decode an uplink IM-RS from a second UE received in the IFDMA comb structure, wherein the uplink IM-RS is time aligned with the downlink IM-RS. The gNB can determine the crosslink interference in the IFDMA comb structure based on the downlink IM-RS and the uplink IM-RS.
